Felix Yz

“If it wasn’t for the fused-with-Zyx thing, I suppose I would just be normal—whatever that means.”
 
When Felix Yz was three years old, a hyperintelligent fourth-dimensional being became fused inside him after one of his father’s science experiments went terribly wrong. The creature is friendly, but Felix—now thirteen—won’t be able to grow to adulthood while they’re still melded together. So a risky Procedure is planned to separate them . . . but it may end up killing them both instead.
 
This book is Felix’s secret blog, a chronicle of the days leading up to the Procedure. Some days it’s business as usual—time with his close-knit family, run-ins with a bully at school, anxiety about his crush. But life becomes more out of the ordinary with the arrival of an Estonian chess Grandmaster, the revelation of family secrets, and a train-hopping journey. When it all might be over in a few days, what matters most?
 
Told in an unforgettable voice full of heart and humor, Felix Yz is a groundbreaking story about how we are all separate, but all connected too.
